  • Patent number: 10687964
    Abstract: A surgical instrument and method for inserting a spinal implant in the intervertebral disc space between two adjacent vertebrae and an anchor engageable with the implant and an adjacent vertebra are provided. The instrument includes an inserter having an engagement portion including a distal engagement surface for interfacing with the implant and a handle portion. The engagement portion includes a track for slidably translating the anchor toward the engagement surface. A kit is provided including the inserter and a tamp to force the anchor into engagement with the implant and the adjacent vertebra. The kit may also include a cutter for piercing the adjacent vertebra.

  • Publication number: 20190224021
    Abstract: A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.

  • Publication number: 20180140439
    Abstract: A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

  • Patent number: 6626907
    Abstract: An anterior cervical plate is disclosed, along with threaded fasteners for securing the plate to vertebrae or other osseous material. The cervical plate has several pockets or apertures, preferably at least four, to receive a corresponding number of the fasteners. The pockets have spherical surfaces, and the fasteners have heads with similarly sized spherical surfaces, which when engaged permit each of the fasteners to be oriented at a variety of projection angles with respect to the plate. In connection with each pocket, the cervical plate incorporates a fastener retaining feature. The feature can take the form of a cantilevered tab or a beam supported at its opposite ends, in each case plastically deformable between an open position for admitting the fastener and a closed position for preventing retraction.

  • Patent number: 6030388
    Abstract: The present invention includes a bone fixation apparatus comprising a bone fixation element, a linking member, and a coupling member. The coupling member has a first channel for receiving a portion of the bone fixation element and a second channel for receiving a portion of the linking member. The first and second channels are configured within the coupling member so as to allow communication of a securing force from the bone fixation element to the linking member such that the bone fixation element is rigidly secured with respect to the linking member. The bone fixation element may incorporate a conical load bearing surface which contacts the linking member through a third channel in the coupling member. Upward axial movement provided by nut tightening forces the load bearing surface of the bone fixation element against the linking member, thereby securing both within the coupling member.
